Street Fighter Collection is the correct name - it had SF2 Anniversary and SF3: Third Strike in it. The reason you're confused is that the pictured artwork is the European cover -(note the 16+ Age Marker).
You're looking for this cover: (PS2 and Xbox)

Second, Street Fighter is probably one of the easiest named brands to follow. There's only 5 series:
Street Fighter
Street Fighter 2 and expansions
Street Fighter 3 and expansions
Street Fighter Alpha and expansions
Street Fighter Vs Series
The Capcom Vs series is a separate entity.
You wanna talk confusing? Try Eidos - they love turning sub-titles into main titles multiple times over :
Blood Omen: Legacy of Kain became...
Legacy of Kain: Soul Reaver became...
Soul Reaver 2...
There are still people asking for Call of Duty 4: Modern Combat 2 ^o^
